How to get the verify value 'v' in ECDSA

Post by scplatform » Tue Aug 28, 2018 9:45 pm

Hello everybody,
I'd like to implement the ETH wallet with javacard, but the signature algorithm of ECDSA in Javacard just return the signature value (R,S), so how can i get the 'V'?

I think you should re-implement your ECDSA api.
